Evolution of stoma accessories – customised stoma seals using individualised bioengineered 3D modelling technology

There is a significant cohort of patients who require the use of paste to fill deficits or creases in their peristomal skin prior to applying their pouching system. For some patients the use of paste can be messy, painful and time consuming. The use of a re-usable individualised silicone device fitting into the crevice or skin fold near the stoma is a new and novel solution. In turn it is hoped to increase wear time of the stoma pouching system, improve quality of life and decrease the financial burden on the Stoma Appliance Scheme.

Royal Perth Hospital Stomal Therapy Service in partnership with the Bioengineering Department has been developing customised silicone stoma seals. The seals are re-usable and are used in conjunction with conventional pouching systems. The seals are designed to fill skin folds or creases that may otherwise contribute to leakage, appliance failure and peristomal skin complications.

Bioengineering undertake a 3D scan of the patient’s abdominal topography in a seated upright position to demonstrate all folds and creases. From this, a reverse mould is 3D printed and an individualised silicone seal manufactured. The Stomal Therapy Service educates the patient on the correct application. A comprehensive evaluation of the device is also being undertaken.  This is proving to be an easier and cost effective solution to potentially complex clinical situations.

Implications for practice within the Stomal Therapy Nursing community could be immense given the cost of service delivery both to an individual, quality of life, health services and the environment.
